This system is not for everyone if you have
CO2 issues it will also be a problem with the KATI ANI system. Regeneration of
resin requires the use Muriatic Acid (31% Hrdrochloric Acid) and Lye (Sodium
Hydroxide).

The recommend tank volume can vary depending
on water hardness and other conditions, but here is a rough recommendation.

Model #2 for up to 200 Gallon tanks

Model #5 for up to 500 Gallon tanks

Model #10 for up to 1000 Gallon tanks

The KATI ANI units are Ion Exchangers which means they adjust
water that flows through the resins by exchanging Ions. The resins give up some
Ions and take in other Ions. This exchange can dramatically affect the chemical
composition of the water.

The KATI and ANI are two separate Ion Exchangers that can be
used singly or together depending on the desired result. This manual will
explain the operating process and regeneration process for filtering tap or well
water prior to adding to the aquarium. This will utilize both the KATI and ANI
units in sequence and will totally de-mineralize the water. The end result is a
very pure water with virtually no hardness or TDS (total dissolved solids)
remaining in the water. KATI ANI units produce very consistent results and they
are generally acknowledged to create 99% pure water. Reverse Osmosis at best is
generally rated at 98% with variability of the results. Other advantages over RO
include no waste of water (which is a significant cost savings), faster
processing time (380 gallons/day), does not need high water pressure to operate,
and no costly replacement of pre-filters, carbon block filters, and membranes.

Other functions the KATI and/or ANI units can perform are
dependent on how the resins are regenerated. The regeneration process defines
what Ions the units will remove from the processed water. The KATI unit alone
can be used to soften water or to partially de-mineralize water. The ANI unit
alone can be used to keep stable pH in a saltwater aquarium. It can also be used
on a temporary basis to polish salt water (reducing Nitrate). Beside totally
purifying tap/well water before using in an aquarium, the combined KATI and ANI
system can be used to temporarily to reduce the total mineral content (including
Nitrate) in a saltwater system, thereby reducing the need for water changes. In
freshwater aquariums, the KATI ANI filtration can be used more often and could
totally eliminate the need for water changes. The regeneration processes for
these alternative uses are more complex and the operation of filtering an
existing aquarium requires close monitoring.

The KATI (red) resin is the only resin that changes color as
it depletes which indicates the remaining life for both sets (KATI and ANI) of
resins. Regeneration is not overly complicated nor does it require expensive
equipment or chemicals. However, the chemicals used are either very strong acid
or very strong base chemicals, which can cause very serious injuries if proper
processes are not followed. The KATI ANI resins are very high quality and have
lasted for over 20 years in some systems.

The various models of KATI ANI run from model 1 through model
10. The model number stands for the number of liters the units hold. So, the
model 10 holds ten liters versus the model 1 with one liter. This means that the
model 10 will process ten times the water (with the same hardness) although at
the same throughput speed. Likewise, the regeneration process will use ten times
more regeneration chemicals in a model 10, but the regeneration time is the
same.

OPERATIONS

The KATI ANI deionizers do not require sediment pre-filters or
carbon filters. Many people still use these filters, which is fine. The sediment
in unfiltered tap or well water will not clog or slow down the KATI ANI
deionization process. Tap water with very high chlorine or derivatives have
caused the KATI resins to bleach over time, which reduces the ability to
visually determine the remaining life of the resin charge. Any type of granular
or block carbon placed before the KATI ANI units will prevent bleaching.

The units are tall in proportion to their base so they should
be either hung securely on a wall or braced to prevent falling if left standing.
However you set up the units, remember that you need to periodically remove the
units to regenerate yourself or send out for regeneration.

The units come plumbed from Germany with a standard 3/8" slip
fit nipples. The recommended tubing is a 3/8" ID semi-rigid white tubing
commonly used to connect automatic ice makers. The German phrase on each unit
states that you should not use a hose clamp. The slip fit works well because the
unit is not to be plumbed under pressure.

The KATI (red) unit is always the first unit to receive water
from your tap or well. This then plumbs into the ANI unit which then plumbs to
your purified water storage. There are two steps involved each time you place
the units in operation (after each recharge). In the first step, you plumb the
incoming tap water into the center hole of the KATI unit. Then you connect the
hose from the outside hole of the KATI unit to the center hole of the ANI unit.
Then the plumbing goes from the outside hole of the ANI unit to a sink or
bucket. Run about 2 gallons of water briskly through this KATI ANI 1 set up.

After this, you are ready to re-plumb the units for continuous
de-ionizing. It is simply a matter of having the water flow in the opposite
direction within the canisters. The flow of water should be re-plumbed as
follows. Incoming tap/well water to the outside hole of KAT, then center hole of
KATI to the outside hole of ANI, then center hole of ANI to water storage.

It is always recommended to aerate purified water at least
eight hours prior to adding to the aquarium or adding a sea salt mix. This is
true no matter what type of filtration is used. Since the deionization process
strips the water of all hardness, it is recommended that you add back some
buffer and calcium so that it does not deplete these items from either the
aquarium or the salt water mix. Raising the Alkalinity dKH to 6 would be a great
start for the buffer side. The first time you purify a batch of water and then
mix the sea salt, measure the calcium level eight hours later. Add calcium until
you reach 400 ppm and note how much calcium additive you used. For future
batches, add this amount of calcium prior to adding to the aquarium or mixing
with salt. Please allow an hour or two between adding the buffer and calcium.

This system is not for everyone if you have CO2 issues it
will also be a problem with the KATI ANI system. Regeneration of resin requires
the use Muriatic Acid (31% Hrdrochloric Acid) and Lye (Sodium Hydroxide).
